• The Prelinger library

    By Chris Tarr

    An unusual field trip offered in this year’s Birdathon is a visit to the Prelinger Library. Do not miss the chance to see this amazing local hidden gem!

    I first learned about the Prelinger Library when I was in the Master Birder program with Megan Prelinger. I’m a retired librarian myself, and the first thing I marveled at was the organization of the material. The library does not follow Dewey Decimal or the Library of Congress classification system, but instead is organized in a way that suited the needs of its first users, Megan and Rick. It uses a “landscape-based, geospatial arrangement system”  starting in San Francisco and ending in outer space. It moves from landscape and nature through artiface (art, media, and culture), abstraction  (society and philosophy) to space exploration.” Here is an overview of the arrangement, or read Megan’s explanation of the arrangement here.  If you have a home library, it’s like what would happen if you had the time and space to arrange all of your materials in the way that made the most sense to you. In browsing a library collection, it’s often the materials next to the thing you are looking for that prove to be the most interesting. The arrangement itself, of course, is as revelatory as anything written with the materials contained. 

    The second amazing thing about the collection is the materials. In an SF Chronicle article written in 2015, Rick says, “We were not so interested in ordinary books that you would see at a public library. We were interested in books that were evidence in a lot of ways, books that had illustrations, books that had underrepresented or suppressed narratives in them.” “Books,” Megan says, “that expressed moments in history rather than told stories about moments in history.” Included in the library are materials they’ve used for research projects of their own,  deaccessioned library materials found on cross country collecting trips including a complete run of the Auk, a collection of New York State forestry documents which include lithographs of every lake in the Adirondacks, all kinds of ephemera. If the idea of the arrangement is serendipity, it’s the depth and uniqueness of the collection that makes that possible. Check out this Stack Explorer to see a few examples of what’s on the shelves. 

    The library was started in 2004, when Rick and Megan pooled their books and records and realized that renting a space for a library would be cheaper than renting storage space.…

  • Six Common Mistakes in Native Gardening

    By Amy Chong

    Native plant gardens are a fantastic way to attract birds and pollinators to your yard — but they’re quite different from other forms of gardening you may have done in the past. Here are six common mistakes that I’ve seen beginner native gardeners make. With a little forethought and planning, you can avoid these pitfalls and create a healthy, vibrant backyard for both you and wildlife.

    1. Planting too close to the house.

    Knowing the mature size of each species before you plant it in your yard is important to give it enough space to grow into a healthy plant. Trees like Toyon (Heteromeles arbutifolia), which produce winter berries for birds like thrushes, thrashers, and Cedar Waxwings, can reach a mature height of 30 feet. Avoid the common mistake of planting a large plant just a few feet from the house, thinking you’ll prune it back each year. Large roots can potentially damage house foundations, and moisture from irrigating the plant can cause water damage. Do what’s healthiest for the plant and for your home—plan ahead and only plant a species that you have enough space for.

    2. Planting too far apart. 

    Are you captivated by the mid-century modern look? Landscaping with modern minimalist design leaves a lot of open space between individual plants. In the wild, however, most plants don’t grow like that. Plants generally grow best when they are in close proximity to each other, as covering the soil prevents desiccation, promotes mycelial networks, and encourages healthy invertebrate life. Plants spaced far apart—even with mulch or gravel covering the ground—have to struggle more to make it on their own. Give your natives friends: know how large they will be when mature and space them appropriately near others, with vertical layers of ground cover, small perennials, larger shrubs, and trees.

    These native plants are spaced well, with strawberry as ground cover, different small flowering perennials, and a small tree—manzanita—arching over in the back. Photo by Amy Chong.

  • Birding the Bay Islands: Mare Island Shoreline & Beyond

    By Helen J. Doyle and Evan Weissman

    Maybe the birds knew Valentine’s Day was just two days away. Love was in the air, literally. Soon after we left the Mare Island San Pablo Bay Trail parking lot, we were stopped in our tracks by two pairs of Northern Harriers in full airborne courtship display, swooping around each other, showing off their legs and feet, and vocalizing back and forth.

    Northern Harriers were also using the sky for stunning displays of romance. Both species are year-round Bay Area residents, feeding on small mammals and birds that also thrive in this marshy, grassland habitat. A thrilling start to birding on Mare Island.

    First though, is Mare Island really an island? Its Spanish names suggest it was at one time – Isla de la Plana (Flat Island) around 1775 and later, around 1834, Isla de la Yegua (Mare Island), renamed by Mariano Guadeloupe Vallejo in honor of his white mare who safely swam ashore here after a boat capsized in the Bay in 1835. Soon after that, in 1854, the US Navy opened its first west coast shipyard here. The Navy and shipbuilding dominated Mare Island for almost 150 years, until 1996, changing its landscape to better suit these industrial purposes. Now Mare Island is a peninsula, bordered by the Napa River and the San Pablo Bay, but it’s easy to imagine that the Napa River once flowed more freely into the Bay, creating wetlands dotted with islands like Mare Island. Today those wetlands make up the San Pablo Bay National Wildlife Refuge. Mare Island is not technically part of this refuge, but its wetlands are also being restored as the decades-long decommissioning of the Mare Island Naval Shipyard continues.

    To get here, we ferried from San Francisco to Vallejo with our bikes and rode over to Mare Island via the scrappy but solid Mare Island Causeway Bridge, built in 1934. We sited a few morning birds along the Vallejo marina and shoreline park before meeting fellow-birders Jon Altemus and Marilyn Nasatir at the San Pablo Bay Trail parking lot. Despite a reputation for single-mindedness, birders are generous about sharing knowledge and teaching others. We laughed about Marilyn’s story of becoming hooked by birds over three decades ago. After a bird walk in Golden Gate Park, for which she had opera glasses but no binoculars, she thought she’d seen just three types of birds.…

  • When birds + letters = art

    By Ilana DeBare

    Birds. Letters. Art.

    It seems natural, given that those are Jeanette Nichols’ loves, that she would create one-of-a-kind watercolors illustrating the letters in people’s names with birds.Like this one: SUSAN = Sandhill Crane, Upland Sandpiper, Scarlet Tanager, American Avocet, and Northern Shoveler.

    Customized name painting by Jeanette Nichols, with each letter represented by a bird.

    Our 2024 Birdathon Adventure Auction is offering one of Nichols’ custom watercolors: the winning bidder can commission Their Name in Birds. But Nichols’ bird-name pieces are only a tiny sliver of the art she’s created over the years. Her Oakland home is festooned with a diverse array of work, ranging from landscape paintings to Hebrew calligraphy to whimsical greeting cards.

    Nichols isn’t a professional artist: she spent her career as an oncology and  hematology nurse at Children’s Hospital before retiring in 2015. But both creativity and birds have been part of her life since childhood.

    “I always drew,” she recalled. “When I was six, we moved to Big Bear Lake in the San Bernardino mountains where my mother ran a motel, which we called a ‘resort.’ There was a chair at the bottom of the stairs with a space behind it. I claimed it as my space where I drew and read. I was either there or outdoors.”

    She inherited a love of nature from her mother’s family, who hailed from Wyoming.

    “When I had trouble learning to swim,” Nichols said, “my uncle pointed out a dipper to me. He said, ‘See that little bird? It can swim. You know you can too.’ Since then it’s always been my favorite bird.” 

    Throughout her adult life, she created greeting cards and small artworks for friends. She provided some of the images for a new prayer book for Congregation Sha’ar Zahav in San Francisco and submitted paintings each year to the Jewish Community Library’s invitational exhibit. For her wedding to Daryl Goldman in 2004, she spent a year learning Hebrew calligraphy to create their ketubah, a Jewish wedding contract.

    Her involvement with birds deepened when she and Daryl took Golden Gate Bird Association’s East Bay Birds class, which was taught at the time by Bob Lewis and Rusty Scalf.…

  • CENTRAL PARK BIRDING — WHY IT’S SPECIAL

    By Ilana DeBare

    What makes birding in New York’s Central Park different from birding in the Bay Area? 

    (Um, you mean beside the hundred or so skyscrapers ringing the park, the 8.5 million people living around it, and the 42 million people who visit it each year?)

    That question was on our minds as we organized this year’s Birdathon Adventure Auction, with prizes that include a three-night hotel stay in Manhattan and a private, expert-led bird walk in Central Park. So we turned to an authoritative source—Glenn Phillips, Executive Director of Golden Gate Bird Alliance, who lived in New York for 27 years, including eight at the helm of NYC Audubon, before returning to his childhood roots in the East Bay.

    Phillips had two answers, one about birds and one about humans.

    The Birds“It’s the abundance of warblers, first and foremost,” he said. “Central Park is one of the best places to see them in spring and fall. In spring, in almost any section of the park, you can get ten species of warbler on any given day. You just can’t do that in California.”

    Beyond warblers, the park offers a variety and density of birds that is remarkable for such a compact area. That’s because of its nature as a unique oasis within a vast, concrete urban area.  Migrants moving north and south along the East Coast stop off in the 843-acre park for rest, food, and water. More than 280 species have been recorded in Central Park, including 192 that are year-round residents or regular visitors.

    “Because it’s this island of green in the middle of the city, the density of birds is much higher,” Phillips said. “You can see more birds in a limited time and space. And when there’s a storm the night before, you get a migratory fallout. The storm sets in at night when birds are already on the move and they look for the nearest open space. The trees are literally dripping with birds.”

     Two of his personal favorite sightings in Central Park have been:

    • Owls. “Central Park is really great for owls. One year there was a group of three or four Long-eared Owls roosting every night in the same tree in the Pinetum.
